Introduction to Infrared LED 8mm

What is an Infrared LED 8mm?

An infrared LED 8mm, also known as an 8mm infrared LED, is a type of light-emitting diode that emits infrared light at a wavelength of approximately 870nm. This type of LED is widely used in various applications, such as remote controls, surveillance systems, and consumer electronics. The 8mm size refers to the diameter of the LED's housing, making it a compact and versatile option for various projects.

Working Principle of Infrared LED 8mm

Infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of an infrared LED 8mm, the semiconductor material used is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied to the LED, it generates infrared light that is invisible to the human eye. The key components of an infrared LED 8mm include the semiconductor material, a metallic contact, a dielectric material, and an encapsulant. The metallic contact is used to apply the electric current to the semiconductor material, while the dielectric material helps to maintain the electrical properties of the LED. The encapsulant provides protection to the internal components and ensures that the LED operates efficiently.
